17 Claims. (Cl. 57-7 This invention relates to machines having multiple pairs of spindles for respectively rotating supply packages of the yarn and cops onto which latter the individual yarns are rewound incident to being twisted by the action of travelers gyrated about. the receiving cops or by flyers, as the yarns are rewound upon the cops. More particularly, the invention is concerned with winding machines wherein the spindles arev driven by separate power devices such as electric motors rather than from a single powered shaft as ordinarily heretofore.

The chief aim of my invention is to simplify the construction of machines of the kind particularly referred to with a view toward attainment of greater uniformity in the treatment of the yarns and increased quantity output from such machines.

These objectives are realized in practice, as hereinafter more fully disclosed, through provision of. winding units each complete in itself and capable of ready removalindividually in the event of mal operation or damage thereto and of replacement with equal facility after being repaired, or replacement by new ones without interfering with the operation of the others and without necessitating stopping of the machines.

Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein:

Fig. 1 shows a broken out view in side elevation, of a multiple spindle yarn winding machine conveniently embodying my invention.

Fig. 2 shows the machine in top plan.

Fig. 3 shows the machine in cross section.

Fig. 4 is a fragmentary view in cross section showing how the component winding units of the machine are individually removable from the supporting frame of the machine; and

Fig. 5 is a view showing a modification of one of the twisting units.

I With more specific reference first to Figs. 1-4 of these illustrations, my improved winding machine, in the form there shown, comprises a horizontally elongate frame comprehensively designated by the numeral 1, said frame having a base 2 which may be fashioned from suitably stout plate metal, and whereto is medially aflixed lengthwise by welding a channel section bar 3. Similarly afiixed along their bottom edges tothe upstanding flanges of the bar 3 are upright metallic plates 4 which are coextensive with the base 1 and which are similarly joined along their tops by an interposed lengthwise-extending channel bar 5. At uniformly spaced longitudinal intervals the upright portion of the frame formed by the side plates 4 is braced by footings 6.

Secured side by side in lateral abutment to the opposite sides of the upright portion of the frame with capac ity for individual removal and replacement, are individual winding units 8. As shown, each'unit 8 comprises a bracket 9 which is fashioned to generally L-shaped configuration from stiff heavy plate metal. The upright am 10 of the bracket 9 is provided along its opposite 2,887,842 Patented- May 26, 1959.

bracket 9 has a pending leg portion 15 which, when theunit is in place, rests upon thebase 2 of, the frame 1. Mounted on anoutward projection 16 at. the top of the vertical arm 10 of the bracket 9 is an electric motor 17 with. a prolongation of its shaft 18- serving as a spindle for an impaled package P of the yarn Y which is to be twisted. A. vertical. axis motor 20 supported adjacent the distal end of the horizontal arm 14 of thebracket 9. has its shaft upwardly prolonged as, at 21 to serveas a spindle for a cop Cv upon which the yarn Y is wound after being twisted. The actual twisting is accomplished after customary practice in this instance by gyration of a traveler 22 about a ring 23 arranged coaxially about the spindle 21, theyarn being passed through the traveler after having traversed a guide 25 fixedly supported on the horizontal arm 14 of the bracket 9. In accordance with my invention, the ring 23 is aflixedto the top of a slide bar 26 which is constrainedv to up and down move.- ment through the horizontal arm 14 of the bracket by a guide formed by two angle. pieces 27 affixed to, the bot.-v tom of said arm. As shown, the slide bar 26:bears upon the periphery of an eccentric actuating cam 28 fast on a. short horizontal shaft 29 rotatably supported in a pro jection 30 pendent from the horizontal arm 14 of the. bracket 9'. As further shown, the cam shaft 29 is driven from the motor 20 through the medium of a system 3L of speed reduction gears. It is to be. understood that, if desired, a twisting means of the flyer type may be utilized instead of the ring type twisting means herein illustrated by way of example.

Protected within a conduit 32 extending, lengthwise through the hollow of the upright portion of the frame 1 near the top are the conductors 33 and 34 of an elec-. tric power line; and affixed to the outer faces of the side plates 4 of the frame 1 at the, locations of the units 8 are socket blocks 35having terminals 35a in circuit with. the conductors 33 and 34. At corresponding locations. on the vertical arms 10' of the brackets 9 of the individual units 8 are blocks 36 with jack plugs 37 whereto the. leads from the respective motors 17 and 20 are connected. Thus, as the units 8 are brought up into. position and the brackets 9 are secured to opposite sides of. the vertical portions 4 of the frame 1 by means of the. nuts 13 applied to the shanks of the bolts 12, the jack plugs of the blocks 36, are entered into the socket blocks. 35 and the motors 17 and 20 are thereby connected to, the line conductors 33 and 34 for supply of electric current thereto.

From the foregoing it will be secnthat the units 8 can be individually removed from the machine in the event of mal operation or damage thereto and replaced after repair, or replaced by new ones in a short space of time without interfering with the others and without stopping the machine. It will be further apparent that by changing the ratio of the gearing 31 associated with the motor 30, it is possible to vary the rate of reciprocation of the traveler ring 23 relative to the speed of the receiving spindle 21 of each unit and hence the compactness of the windings of the yarn on the cop C.

As a modification, the cam 28 for vertically reciprocating the traveler ring may be driven, as shown in Fig. 5 by a motor 40 separate from the motor 20 which drives the cop spindle 21, the additional motor having incorporated therewith a speed reducing gearing 41 and being supported by a suspension 42 from the horizontal arm. 14 of -the bracket 9.. In. order to dispense with the.

necessity for repetitive description, all the component elements shown in Fig. 5 and having their counterparts in the first described embodiment, are identified with the same reference numerals previously used.

Here likewise, by changing the ratio of the gearing 41 associated with the motor 40 of the winding unit, the rate of reciprocation of the traveler ring 23 may be varied as may be desired or required as in the first described embodiment.

While in accordance with the provisions of the statutes, I have illustrated and described the best forms of embodiment of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus described without departing from the spirit and scope of the invention as set forth in the appended claims, and that in some cases certain features of my invention may be used to advantage without a corresponding use of other features.
